AMALGAMATOR.

Specification of Letters Patent No. 30,783, dated November 27, 1860.

To all whom it may concern:

Be it known that we, JOHN N. WYoKorr,

of Brooklyn, in the county of Kings and State of New York, and THOMAS M.FELL, of Melvin Mines, in the county of Orange and State of Virginia,have invented a new and Improved Gold and Silver Amalgamator; and we dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the anneXed drawings,making a part of this specification, in which Figure 1 is a verticalsection of our invention taken in the line 00, m, Fig. 2.. Fig. 2, avertical section of the same taken in the line 00, 00, Fig. 1.

Similar letters of reference indicate corresponding parts in the twofigures.

This invention relates to certain novel mechanical means employed foreffectually carrying out the process of reducing gold and silver oresfor which process Letters Patent were granted to us hearing date July26th 1859.

The within described invention consists in admitting steam within aclose vessel and in jets through stirrers or agitators, the steam beingadmitted directly into the pulp and mercury and serving to aidamalgamation both by heat and a mechanical action, as hereinafter fullyshown and described.

To enable those skilled in the art to fully understand and construct ourinvention we will proceed to describe it.

A, represents a framing which maybe constructed in any proper manner tosupport the working parts of the machine.

B, is a vessel which is placed on the framing A, and provided withcovers or lids a, and O, C, are tubes or hollow shafts which are placedlongitudinally on the upper part of the vessel B, and project about halfof their diameter through the top of the vessel as shown clearly in Fig.2.

The shafts C, C, are fitted in proper bearings b, and into the outerends of said shafts steam tubes D, pass said tubes communieating withany suitable boiler.

To the upper surfaces of the shaft C,

there are attached upright frames E, E, one to each, and the upper endsof these frames are connected by rods 0, to a crank shaft F, the latterbeing driven by any convenient power. To the under sides or surfaces ofthe shafts C, C, there are attached frames G, G, the lower parts ofwhich are perforated so as to form vertical slats (Z, as shown clearlyin Fig. l. The slats d, are connected at their lower ends to horizontaltubes 6, e, a tube 6, being to each frame G, and the outer ends of thetubes 6, communicate with the lower ends of upright tubes 7, f, whichextend upward and communicate with the hollow shafts C, C, as shownclearly in Fig. 1. The tubes 6, are perforated at their underside asshown at e.

The bottom of the vessel B, is of curved form, being the segment of acylinder of which the shafts C, C, are the center, and the tubes 6, arequite close to the bottom of the vessel B. To one end of the vessel B,there is attached a trough H, which may communicate with the vessel B,when necessary by opening a screw valve I, seen in Fig. 1.

The operation of the machine is as follows: The vessel B, is suppliedwith a requisite quantity of mercury and'the pulp or crushed ore islaced within the vessel B. The shaft F, 1s then rotated and the shaftsC, C, rocked back and'forth. The frames G, G, serve as stirrers oragitators, and steam which is admitted into the shafts C, 0, through thetubes D, passes down the tubes f, f, into the tubes 6, e, rushes throughthe perforations 6, into the pulp and mercury, heating the same to aproper temperature to favor amalgamation and by rushing into the mixtureproducing a mechanical action which aids that of the stirrers or framesG, in bringing the several particles of the pulp in contact with themercury.

After the metal contained in the pulp has been amalgamated, the contentsof the vessel B, are drawn off by opening valve I, and the contentspassed over a shaking table as usual to separate any stray particles ofamalgam. Waste steam may escape through a pipe A, which communicateswith the cury; substantially as and for the purpose upIpIer part lpfvessel 1361 h set forth.
